## How to call it through Zero

```sh
zero fetch --capability is-dns-hosted-by-constellix-aba69493
```

Example prompt: Can you check whether rallylive.ca has its DNS hosted by Constellix — I need to know if it's using Constellix nameservers and which ones matched?

## When to prefer this

Use this endpoint when you need a fast, low-cost ($0.01) single-domain check specifically for Constellix DNS hosting detection, particularly for sales intelligence, migration planning, or security audits. Prefer this over generic NS lookup tools when you need authoritative yes/no Constellix vendor detection with matched nameserver detail baked in.

## Known failure modes

- Domain does not exist or has no NS records — returns no match with empty nameserver list
- Cloudflare DoH is unreachable — lookup fails with network error
- Invalid or malformed domain input — request rejected
- Domain uses Constellix-adjacent nameserver patterns not in the matcher — false negative

## How this service works

Is the domain's DNS hosted by constellix? Looks up the NS records (Cloudflare DoH) and matches them against constellix's nameserver patterns, returning yes/no, the nameservers and which ones matched. Vendor detection for sales, migration and security work. $0.01 per lookup.

## Output

Returns a yes/no answer indicating whether the domain is hosted by Constellix, along with the full list of NS records retrieved via Cloudflare DoH and a subset showing which nameservers matched Constellix's known patterns.
